F F l C i CONCRETE-INSERT.

T0 all whom it may concern.'

Be it known that l, JOHN EDWARD UGDEN, a citizen of the United States of America, and a resident of Mountainville, town of Cornwall, Orange county, and State of New York, have invented certain new and useful Improvements in Concrete-lnserts, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to limprovements' in concrete inserts for the reception of bolts and the like, and its object is to provide a simple and inexpensive device for this purpose which is easy to install and which pro vides for a maximum adjustment of the position of the bolt.

ln ord-er that my invention may be thoroughly understood l will now proceed to describe the same in the' following specifi cation and will then point out the novel features thereof in appended claims.

Referring to the drawings:

Figure 1 is a sectional side elevation of an insert which is made according to and embodies this invention and a portion of a concrete floor in which it is embedded, together with a bolt supported bythe insert.

Fig. 2 is a sectional end elevation of the same parts. The section in this figure is taken on the line 2-2 of Fig. 1.

Fig. 3 is an inverted plan view of the insert and the bolt, the shank of the bolt being shown in section.

Fig. 4 is a sectional side elevation'of an insert of modified construction with a nut therein.

Fig. 5 is a sectional end elevation of the insert shown in Fig. 4. the section being taken on the line 5-5 of Fig. 4f.

Like characters of reference. designate cor`v responding parts in all the figures.

10 designates a rectangular box-like housing open at the bottom. 11--11 are inwardly projecting ianges along the lower edges of the housing.' Opposite parts of these flanges are cut off to form beveled ends 12 and 13. 14 are outwardly. projecting hooks lat the ends of housing and 15 are other hooks projecting upwardly from the housing and facing toward each other. These hooks are provided f0.1 the Purpose 0f Specification of Letters Patent.

receiving the reinforcing rods 2O in the conf crete body 21. From the lower edge of the housing near the center thereof, lugs 16 which are notched as at 17, project outwardly. rlhe lower surfaces of these lugs are preferably slightly above the lower edges of the housing 10.

30 is a flap, pivoted to the housing by a pin 31. The free end 32 of this ap is bev- A f eled to rest upon the beveled ends 12 of the Hanges 11, and another part 33 is beveled to rest upon the yfianges at 13. The free end is .cut away as shown at 3% to form continuations of the flanges 11.

Before more specically describing the last two figures of the drawings, l will describe the use and operation of this device. The housing is placed upon the mold board beforethe concrete is poured and may be iXed in desired position, by nails 37 or the like, which are driven into the mold board through the notches 17 in the lugs 16. Then v the reinforcing rods 20 may be sprung under the downwardly facing hooks 14 and 15 after which the concrete is poured over the device completely embedding it but leaving the lower edges of the housing flush with the under surface of the concrete. After the concrete is set and the mold board removed, the lower ends of the nails 37 may be bent up out of the way as shown at 38 (Fig. 2).

rlhe head 41 of a bolt 4:0 may now be pushed up into the housin through the trap formed by the pivoted ap 20. 'llhls operation will push the flap up into the position in which it is shown in broken lines at 30A in Fig. 1, but it will immediately drop down to form a continuation of the iianges 11. The head 41 of the bolt will now rest on these iianges. llf desired, a' nut may b e inserted instead of a bolt head.

1t may be seen that the ,bolt is free to be moved longitudinally throughout the length of the device for adjustment. The distance B (Fig. 3) between the flanges is slightly less than the distance A from one edge of the shank of the bolt to the opposite edge of its head. This holds thev bolt from being pulled out but permits a lateral adjustment of its position. The distance between the opposite sides of the housing iS less than the maximum transverse dimension of the bolt `no fiap. An opening 50 is provided in the upper part of the housing, of sufficient size t0 permit the insertion of a nut 42. When this form of the invention is used, the nut is inserted before the concrete is poured yso with the housing.

andthe opening 5() closed by a'stopper 51. The nut is retained as before'and after a bolt is screwed into it its position may .be d

adjusted longitudinally and laterally, but the nut cannot be removed as it can when the flap is provided.

vNo structural limitations are intended other thanthose imposed by the appended claims. l.

What I claim is: l 1. A concrete insert comprising a box-like housing open on one side Ahaving parallel side walls and flanges near opposite edges of said side walls extending inwardly therefrom in a plane normal to the planes of said side walls and extending substantially throughout the length of said side wallsl for supporting the head of a bolt or nut, a part of at least 011eV of said flanges being inwardly movable to permit the insertion of a bolt head or nut.

2. A concrete insert comprising a box-like housing open on one side having parallel side walls and inwardly extending flanges near opposite edges of said sidel wallsv throughout the length thereof for supporting the head of a bolt or nut, a part of at least one of said flanges being inwardly movable out of its normal plane to permit the insertion of a bolt head or nut.

3. A concrete insert7 comprising a box-like housing open on one side having inwardly extending ianges near opposite edges of its open side and shorter than said side for supporting the head of a bolt or nut, and a flap at the ends of the flanges pivotally connected 4. A concrete insert comprising a box-like housing open on one side having inwardly extending fianges near opposite edges of its open side for supporting the head of a bolt or a nut, and a fiap pivotally connected with the housing, parts of said flap forming in one position of the liap, continuations of said flanges. f'

5.. A concrete insert comprising a box-like housingropn on one side having inwardly extending flanges near opposite edges of itsvopen side for supporting the head of a bolt or nut, and a flap pivotally connected with the housing, parts of said flap forming in one position` of the flap, continuations of said'fianges, the free end of the flap being arranged to rest upon the ends of the flanges. x

6.' A concrete insert comprising a box-like housing open on one side having-inwardly extending flanges near opposite edges of its open side for supporting. the head of a bolt, the ends of said flanges being beveled, and a Afiap pivotally connected with the housing having beveled portions at its'free end and arranged to rest upon thebeveled ends of the flanges and parts of said flap forming in one position of the flap, continuationsXof said flanges.

' 7 A concrete insert comprising a box-like housin 4open on one side having inwardly extending flanges near opposite edges of its open side for supporting the head of a bolt, opposite portions of said flanges being cut away `to form oppositely beveled ends, and a flap transversely pivoted to the housing adapted `in one position to rest upon the beveled ends of the anges and to form continuations thereof.

8. A concrete insert comprising a housing having an open side, a pivotally supporte flap arranged to partially close the open side and to be moved in one direction about its support to permit the insertion .of the head or nut of a bolt, and means for preventing movement of the flap about its support in the opposite direction beyond its side closing position.

9. A concrete insert comprising a housing having an open side, a flap pivoted near one of its ends to said housing near, one end of the housing, arranged to partially close the open side and to'be moved in one direction about its pivot to permit the insertion of the head or nut of a bolt, and means for preventing movement' of the iap about its pivot 'in the opposite direction beyond its side closing position.

10. A concrete insert comprising a housing having an open side,'a flap pivoted to said housing arranged to partially close the open side` and to be moved in one direction about its pivot to permit the insertion of the head or nut of a bolt, and means for preventing movement of the liap about its pivot in the opposite direction beyond its side closing position, said flap being constructed to form in its side remote from its pivot a recess of less width than the smallest trans- 1.yei'se dimension of the head-or nut of the o t. L
